10 Low-Volume-Sampler 2 ISAP1050e ISAP - Gerhard Schulze
Automatisierungstechnik
Aerosol sampling devices used for the determination of PM10, PM2.5 and PM1.
Additional temperature, air pressure, humidity, precipitation and wind sensors.
11 Analytical Balance 1 ABT 120-5DM Kern & Sohn GmbH
Used for precise and accurate filter weighing.
12 GPS 1 450T Oregon Garmin
Used for determination of precise location of measurement instruments.
13 Laserscanner 1 ILRIS 3D Scanner Optech
The device is used in capturing surface area pictures in field from a distance of up to 1200m. The site data is then transformed in 3-D digital models.
By scanning and modelling a particular area at various timeframes, changes in geometry can be quantified up to micro level.
The device has been used for measuring the volumetric changes as result of erosion at mine waste rock dumps in Vietnam.
